Alfredsson, who also scored in Monday's 6-5 shootout win over Toronto, tied it at 2 late in the second period with a short-handed goal. He added his fifth of the season on a power play at 14:35 of the third to put Ottawa up 4-2.

The Senators captain liked what he saw from Emery, who made his first appearance after regular goalie Dominik Hasek got Ottawa's season off to a 3-0 start.

``He played great and he looked really calm in there, not nervous at all,'' Alfredsson said. ``It was nice to see. He came in and made the big stops when he needed to.''

Antoine Vermette gave the Senators their second lead of the game 2:58 into the third period when he redirected Chris Phillips' point shot past Jose Theodore, who complained in vain that Vermette interfered with him just before the shot.

``There was contact,'' Theodore said. ``Yes, he got out of the way, but it put me out of position.''

``We've tried to discuss that about giving the defensemen a chance to maybe help out our goaltenders a little bit more,'' Julien said. ``Listen, these new rules, it doesn't mean they're perfect. They're good, we need to adjust to them and hopefully down the road we'll make some small adjustments to them.''

Phillips also assisted on Zdeno Chara's first of the season, which opened the scoring 2:27 in.

Emery assisted on Alfredsson's short-handed effort at 18:55 of the second.

``It was a situation where I didn't know if I was going to get a chop at the puck, because it was in that little corner there,'' Emery said. ``Once it came out, I just whacked it around and the guys threw it up and Alfie buried it, so it was cool to get on the scoresheet, too.''

Saku Koivu and Steve Begin scored for Montreal, which drew a capacity crowd of 21,273 for its home opener after the Canadiens won their first three road games.

Chara beat Theodore with a slap shot from the point to put Ottawa ahead early, but Montreal tied it at 14:26 of the first when Koivu put Alexei Kovalev's pass from behind the net past Emery from the edge of the crease.

Begin scored a short-handed goal 7:48 into the second, taking a flip pass from Tomas Plekanec while he was covered by Dany Heatley and redirecting it into an open right side.

Alfredsson quieted the crowd with 1:05 left in the period when he put a shot through the legs of defenseman Francis Bouillon and past Theodore to tie it.
